Abstract

The results of this dendrogeomorphological study provide evidence of the active movement of Hilda rock glacier. The samples were crossdated using locally and regionally developed tree-ring chronologies, and were shown to have been killed between 1576 and 1999. The results show that Hilda rock glacier has advanced at an average rate of 1.6 cm/year since the late 1790s, with limited evidence of similar rates of activity extending back to the mid-1570s. This rock glacier activity is believed to be linked to persistent periglacial processes that appear to be independent to the climatic forcing mechanisms known to influence glacier mass balances over the same interval
